ing pump end to suction check valve on pump. Observe the following instruction:

1. Use adequate pipe sizes, never smaller then ¾" except

under positive suction head (see page 4). Where total pipe length between pump and source of supply is over 25 ft., use the following table to determine pipe size. An increaser ﬁtting will be required at pump.

Total Length of Suction Pipe Between Pump And Well

Size Suction Pipe

Up to 26' to 101' to

25' 100' 300'

¾" 1" 1¼"

Note: The total suction lift, which includes the vertical distance between the pumping level of the water and the pump plus the friction loss in the pipe should not exceed 25 feet.

2. All piping or tubing should be inspected to make sure

it contains no scale, dirt or other foreign material that might impair operation of pump.

3. All joints must be air tight. A good pipe compound

should be used.

4. A union should be installed in the suction line close to the

pump. Packed unions are preferable. If ground unions are used they must be carefully aligned.

5. On suction lines 50 feet or more in length, a foot valve

can be used to lessen priming time. Install a tee in the suction line for priming. When a foot valve is used, prime pump through priming opening and suction line through opening in tee.

6. Dug or drilled wells should be vented.

DISCHARGE PIPING

Connect house service pipe to ¾" discharge opening. A gate valve in the discharge line close to the pump will facilitate working on pump without draining entire house system.

WATER HEATERS

A check valve should be installed close to pump in the discharge line between pump and water heater or other heating appliance to prevent hot water from entering pump. Be sure water heater or other heating device is equipped with a temperature and pressure relief valve.

WIRING

Do not run pump until it has been ﬁlled to the priming opening with clear water (see

PRIMING, page 4).

Standard motors furnished are 115/230V, single phase, 60 Hz, A.C. motors.

Dual voltage motors will be wired for 115 volts. They can be changed to 230 volts by following the instructions on the motor or on the nameplate.

1. Use wire of sufﬁcient size to maintain adequate voltage

at motor terminals while pump is running. Voltage variations of plus or minus 10% from nameplate value are allowable at motor terminals.

2. Motor circuits should be properly protected according

to NEC, CSA, state, provincial and local electric wiring codes.

WARNING

3. A manual disconnect switch should be located close to

the pump where required by code.

4. It is recommended this pump and motor be grounded in

accordance with prevailing electrical codes. Provisions are provided for attaching ground wires to both motor and pressure switch. Ground screws are located under motor end cover and in the pressure switch.

IMPORTANT: After connecting wiring, DO NOT RUN PUMP until it has been ﬁlled to priming opening with clean

water. Connect power from a dedicated grounded circuit to the

Line terminals on the pressure switch. The connection between the switch and the motor is made at the factory. The circuit breaker should be OFF when the connections are made by a qualiﬁed electrical technician.

INSTALLATION WITH POSITIVE

SUCTION HEAD

On installations where the pump takes its water from a source of supply that is at a higher elevation than the pump, the pump operates under what is known as positive suction head.

When the BF03S is used on this type of installation, install a partially closed ball valve in the suction line to create suction head at the pump.

To determine if a suction lift has been created, disconnect tube from air volume control. With pump running, air should be taken into tube. This can be determined by placing ﬁnger over end of tube. When reconnecting tubing, be careful not to cross the threads. Be sure the joint is air tight.

OPERATION

After making absolutely sure that the power

is OFF, remove the motor cover. Check that the impeller turns freely. Turn the centrifugal switch mechanism by hand or with a screwdriver. If the shaft turns freely, reinstall the cover. On a new pump, if the pump is bound the motor may have been damaged in shipping. Return it to the place where purchased.

PRIMING INSTRUCTIONS

Prime the pump by removing the priming plug on the motor adapter and ﬁlling the casing with water. It should hold about 3 quarts. Replace the priming plug and open the faucet closest to the pump. See Figure 1.

Pump is now ready to be started. Check all plumbing connections and then turn power ON.

Pump should pick up prime within a few minutes. The longer the suction pipe the longer it will take to prime. If the pump does not prime turn power OFF and check for air leaks on suction piping and on the Air Volume Control tubing and ﬁttings. Repair all air leaks, reﬁll casing with water and start pump by turning power ON.

After the pump is fully primed, open a few more faucets. When all air is expelled from the plumbing and the water ﬂows steadily close the faucets. Pressure should build up to 40 psi and the switch should turn the pump OFF. The pump is designed to run continuously whenever water is being used and to turn OFF only when water usage (ﬂow) stops. If the switch does not go off it may require a minor adjustment.

DANGER

motor running. This adjustment should be made only by qualiﬁed technicians familiar with working on “hot” electrical devices. Remove the switch cover and locate the tallest and largest spring/nut assembly. Turn the 3⁄8" hex nut counterclockwise to lower the cut-out pressure. The safest tool to use is a 3⁄8" nut driver with a hollow shaft, next best is a 3⁄8" box end wrench. One full turn changes the setting 2 psi. After adjusting the OFF setting it will be necessary to run through a cycle to insure that the pump runs continuously when you use water. Do this by opening 2-3 faucets for a few minutes and then close them. Pump should go to approximately 40 psi and turn OFF. Reinstall the switch cover and tighten the screw.

Note: Extreme seasonal variations in the well water level may require adjustments to the switch to prevent rapid cycling or to allow the pump to shut off. The switch adjustment instructions are on a label inside the switch cover.

MAINTENANCE

MECHANICAL SEAL

The mechanical shaft seal in this pump is not adjustable. If a continuous and steady leak occurs around the shaft it is an indication that the mechanical seal needs replacing. To replace seal, observe the following instructions. See Repair Parts page for part identiﬁcation/nomenclature.

REPLACEMENT OF MECHANICAL SEAL To Dismantle:

Turn off power on pump motor branch circuit and disconnect line wires to pressure switch. Close valve in house piping. Drain pump. For procedure, see Seasonal Service Instructions.

Remove 8 hex bolts holding motor adapter to pump casing and lift off rotating element assembly including motor and motor adapter.

Place motor and rotating element assembly on table, bench or other convenient working space and remove guide vane bolts and take off guide vane. See ﬁgure 4.

A.O. SMITH MOTORS - Remove motor end cover. Insert

⁄16" open end wrench, under switch mechanism onto ﬂats on motor shaft. While holding the shaft against rotating, turn the impeller counterclockwise. The impeller should turn completely off the shaft in this manner. See ﬁgure 2.

Using two screwdrivers, pry out rotary seal assembly. See ﬁgure 3.

Using two small screwdrivers pry out the stationary seal and Buna cap.

The pressure switch adjustment must be made with the power ON and the pump

Figure 2

Figure 3

To Reassemble:

Be sure that recess for seal seat is free of all dirt and scale. Apply a thin ﬁlm of light oil to the recess of the motor

adapter and the neoprene bushing before installing the new seal seat. This is a tight ﬁt, but it must go in all the way evenly or a leak will result. It can be pushed in with the two thumbs. Do not mar lapped face of this seal. The slightest scar or particle of dirt will cause a leak.

Assemble rotating member of seal on motor shaft. Rotating seal face must ﬁt snugly against lapped seal face of stationary member in motor adapter. This is accomplished by placing the rotating seal, sealing face toward stationary seat, on the shaft. Use the impeller to drive and seat the rotary seal.

Place gasket on motor adapter being careful the holes in gasket line up with openings in the adapter. If gasket is badly worn or has been damaged in any way, replace with a new one.

While holding the shaft against rotating, as described in A.O. Smith motors, page 4, screw impeller on shaft by hand until tight against shoulder of motor shaft.

Replace guide vane, making sure that bore of guide vane does not bind impeller hub, tightening screws alternately and evenly. This can be checked by turning the motor shaft. If binding occurs, loosen screws, re-adjust guide vane until impeller hub turns freely, then tighten screws as before.

LOCATING TROUBLE

IF YOUR UNIT FAILS TO FUNCTION PROPERLY

If your Goulds Water Technology BF03S Water System fails to operate properly after the foregoing instructions have been followed, the trouble can usually be traced to certain simple causes. Such as inadequate priming, air leaks in the suction line, foreign matter in system, low voltage in power line causing low motor speed, insufﬁcient ﬂow from well or other source of supply, excessive suction lift, or a house service line that is too small or too long causing excessive friction loss. The following suggestions for locating troubles should be followed in the order given, making sure that each step does not remedy the trouble before trying the next one.

IF PUMP RUNS BUT DOES NOT DELIVER WATER NOTE: On long suction lines it may take considerable time

for the pump to exhaust all of the air in the suction pipe and start to deliver water. When starting the pump under these conditions, always leave a faucet open for the air to escape. If there is a foot valve on the end of the suction line, ﬁlling the suction piping with water before starting will shorten the time required for the pump to start delivering water.

1. Examine pump by removing priming plug to see if it is

full of water. NOTE: Three quarts of water poured in priming opening is sufﬁcient to prime pump.

2. Check source of supply to see if there is an ample supply

of water available and that the end of suction pipe is submerged in water but not buried in mud.

3. Check motor rotation. Make sure that motor runs in

direction indicated by arrow on pump casing cover.

CAUTION

valve stem with your ﬁnger to be sure it operates freely and no foreign matter is present to prevent it seating.

5. Disconnect tube from air valve and place tire valve cap

on end of air valve. If pump primes OK it indicates that the tube connections have been damaged and allow air to leak into the suction of the pump. When reconnecting copper tubing be sure threads are not crossed and the connections are made air tight. See Procedure and Diagram for making these connections.

VACUUM GAUGE METHOD FOR TESTING SUCTION

Disconnect air volume control tube from air valve in pump chamber. Remove air valve and insert vacuum gauge in 1⁄8" pipe tapped opening in back plate. See ﬁgure 1. Run the pump. If while pump is running, gauge does not register vacuum it indicates:

A. Leak or leaks in the suction line. B. End of suction pipe is not submerged.

If gauge registers a vacuum of 25" or more it indicates:

A. Plugged strainer on end of suction line or

strainer is buried in mud.

B. Suction check valve plugged or inoperative. C. Too high a suction lift for satisfactory operation.

If gauge registers a vacuum in feet that is less than the vertical distance between the pump and the water in source of supply, it indicates a leak which must be located and eliminated. Most frequent causes of leaks in suction line are ground unions, split pipes and ﬁttings. Check these sources for leaks ﬁrst and repair them.

Remove vacuum gauge. Replace air valve. Reconnect copper tube making sure all suction side connections are tight, as they must be air tight.

If pump fails to function after vacuum gauge is removed and air volume control is reconnected it indicates the tube connections are not air tight.

IF PUMP DELIVERS WATER BUT PRESSURE SWITCH DOES NOT STOP PUMP WHEN WATER IS NOT BEING USED

To determine cause of the condition, proceed as follows:

1. Close valve in house piping system if one is installed. If

pump stops it indicates leaks in house piping. Examine toilet ﬂush valves, faucets, etc., for leaks.

2. Check motor rotation. Make sure that motor runs in

direction indicated by arrow on pump casing cover.

3. Check for excessive suction lift. To do this, see vac-

cum gauge method under section “IF PUMP RUNS BUT DOES NOT DELIVER WATER”, page 5. If suction lift

is beyond suction limits of pump, provision must be made to reduce the suction lift by placing pump closer to source of supply.

4. Pressure switch may need readjustment. See instructions

for setting pressure switch.

5. Check suction line for air leaks. See paragraph under

section “IF PUMP RUNS BUT FOES NOT DELIVER WATER”, for method of doing this.

6. Air volume control tubing or ﬁtting may be leaking air.

7. The nozzle might be plugged. In order to make a proper

examination of the nozzle and venturi, they must be removed from the pump. To do this:

A. Disconnect power from pressure switch, close

gate valve in house piping and drain pump.

B. Remove 8 tap bolts holding case cover to case

and lift off rotating element assembly including motor and case cover.

C. Disconnect the suction and discharge pipes and

copper tube from air valve.

D. Remove the 4 tap bolts holding the back plate

with nozzle and venturi to cushioning chamber and remove this assembly from the chamber.

E. Venturi can be readily unscrewed and taken out

with a strap wrench or small pipe wrench.

F. To remove the nozzle use a 5⁄8" socket wrench. G. Check number stamped on nozzle. This should

be 015.

When replacing nozzle and venturi be sure they are screwed in tightly as the shoulder of each must ﬁt tight against the machined surface of the back plate in order to give the proper spacing of these parts, which is very important for the satisfactory operation of the pump.

NOTE: It is recommended that thread on the plastic venturi be lubricated with water. Be sure thread starts properly and venturi is screwed in up to shoulder.

When reassembling the pump be sure the

gaskets are in good condition and properly placed and that the guide vane seal ring is in position on the venturi.

IF, AFTER PUMP HAS BEEN IN SERVICE FOR SOME TIME, IT PUMPS WATER BUT DOES NOT SHUT OFF WHEN WATER IS NOT BEING USED.

If pressure switch has been adjusted several times over a long period of time and the condition is not corrected, it is probable that the radial clearance between impeller hub and guide vane is excessive. Remove rotating element and check this clearance. If clearance is excessive (more than .020") or parts are deeply scored they should be replaced. Install a new guide vane and impeller which will restore pump to its original condition.

IF PUMP STARTS AND STOPS FREQUENTLY WHEN WATER IS NOT BEING USED

1. Examine entire house piping system for leaks such

as dripping faucets and leaky ﬂush tank valves and eliminate any leaks.

2. Examine suction check valve. An obstruction on seat

would permit water to drain out of pump and cause pump to start frequently. Make sure that suction check valve stem moves freely in guide and that valve seats tightly.

3. This condition of frequent starting and stopping when

water is not being drawn may be due to a lack of air in the air cushioning chamber which may be caused by improper operation of the Air Volume Control or Air Valve.

If a water-logged air cushioning chamber exists, when water

CAUTION

is not being used, which is indicated by a rapid starting and stopping of the pump, recharge the air cushioning chamber by disconnecting the copper tube from the air valve, and let the pump run with a faucet open until air comes out of the faucet. Then reconnect copper tube with pump running. To prevent repetition of this condition check air volume control and air valve.

AIR VOLUME CONTROL

This is not a standard Air Volume Control. Be sure to use the special model supplied by Goulds Water Technology for this unit as it has a custom spring tension setting.

WHY IT IS NECESSARY

The turbulence of the water as it passes through the casing causes it gradually to absorb air. Without air replenishment, the water level would rise and soon there would be no air in the cushioning chamber . . . a water logged condition.

The Air Volume Control and Air Valve on Goulds Water Technology Balanced Flow Water System are vitally important parts of the unit. All connection to Air Volume Control and Air Valve must be air tight. Without these parts operating properly, satisfactory functioning of the entire unit cannot be expected.

HOW IT WORKS

The Air Volume Control is installed in the tapped opening in the air cushioning chamber. It must be connected to the Air Valve in the body of the water pump with copper tubng. See ﬁgure 5.

The ﬂoat of the air volume control rises when the water level rises. The extension of the ﬂoat rod in the air volume control (on the outside of the air cushioning chamber) pushes the valve stem (1) in diagram down, opening valve. This exposes the end of copper tubing to atmosphere through hole in nameplate. Suction of the water pump takes air in through this hole, down the tubing and into the water pump through Air Valve (2). The air passes into the air cushioning chamber with the water as it is discharged from the water pump.

When there is sufﬁcient air in the air cushioning chamber the water level is at or below the level of the ﬂoat valve, valve (1) is closed and no air is drawn in until it is required.

WATER LOGGED (AIR CUSHIONING CHAMBER) CASING

A pump casing is water logged when there is no air in it . . . it is ﬁlled with water. It can be caused by:

1. Plugged oriﬁce, damaged valve core or ruptured ﬂoat on

air volume control. To check air volume control and air valve, proceed as follows:

A. Disconnect copper tube from air volume

control. When pump is running, air should be drawn into tube. If air is not drawn into tube, the air valve may be plugged.

Pump must have suction lift to draw air through tube. See section “INSTALLATION

UNDER POSITIVE SUCTION HEAD”, page 4.

B. Remove air valve. Blow through it from tubing

connection side. If plugged, take it apart and clean. Replace valve core if necessary.

C. Remove replacement valve assembly from the

air volume control and remove the valve core from the valve body. Hold valve body to the light and if you cannot see light through it, oriﬁce is plugged. Clean with a needle or very ﬁne wire. If unable to clean, replace with a new one.

If valve core is damaged, replace with a new one.

2. Air Volume Control may be inoperative due to punctured

ﬂoat, broken ﬂoat rod or ruptured diaphragm around ﬂoat rod. Replace with new one.

IF WATER LEAKS AROUND AIR VOLUME CONTROL

1. Disconnect copper tubing at Air Volume Control. If leak

comes from tubing, Air Valve in water pump is leaking. Replace valve core. See ﬁgure 5.

2. If water leaks from Air Volume Control when tubing is

disconnected, the control should be replaced.

SEASONAL SERVICE

TO TAKE OUT OF SERVICE

When pump is used during summer months and allowed to stand idle during the winter, as in summer cottages, it is necessary that the pump be thoroughly drained to prevent damage from freezing. To drain unit proceed as follows:

1. Shut off power to pump motor branch circuit.

2. Drain house service lines.

3. Disconnect union in suction line and drain line. If there

is a foot valve on end of suction line it must be removed and line drained.

4. Remove drain plug near bottom of air cushioning

chamber and allow all water to drain out. Removal of priming plug will allow pump to vent while draining. When removing drain plug make sure that tapped opening from which plug is removed is not clogged with scale or mud. If there is any question of foreign matter in the opening, it should be cleaned out with a nail or piece of stiff wire so that water will drain out freely.

5. After pump is completely drained, replace plugs. TO PLACE PUMP BACK IN SERVICE

1. Make sure drain plug previously removed is tight. Use a

good joint compound on threads and screw in tightly.

2. If well pipes have been removed, reconnect them.

Examine faces of ground union. If scored, pitted or imperfect, make packing of sheet rubber to insure tight joint. If foot valve has been removed, reinstall.

3. Remove motor shaft end cap, insert screwdriver in motor

shaft slot and turn clockwise to make sure pump is free.

4. Prime and start. See Priming and Starting and Setting

Switch Instructions.
